超形变核态研究的进展

Nuclear Superdeformed States

简单回顾了超形交(SD)核态的近期进展,着重介绍了SD转动带的唯象分析,包括SD带角动量的确定,运动学和动力学转动惯量随转动频率的变化及其相互关系等。给出了说明所谓“全同”SD带的一个可信的方案,与现有的微观理论计算是一致的。在此方案中毋需引进赝自旋顺排的概念。

The recent development of the investigations of nuclear superdeformed (SD) states are briefly reviewed with emphasis on the phenomenological analyses of nuclear SD rotationa' bands, including the determination of the angular momenta of SD bands, the variation of the kinematic and dynamic moments of inertia with rotational frequency and their mutual relation, etc. A plausible scheme to account for the so-called 'identical' SD bands is given, which seems to be consistent with the available microscopic calculations and in which no pseudospin alignment is involved.
